Formed in either of the'upper side frames 21 and 22- are the bearings23. and 24 and passing through the 'bearing 23 is the shaft 25 on theouter end of which the pinion 26 is secured, and a rack 27 which isactuated by the ram 28, is. adapted to actuate the said pinion thusrevolving the shaft 25'. The said shaft has a squared portion 29, nearthe bearing 23 and upon this squared portion 29 the member 19 of thedrum is secured. This shaft is again formed round as at 30, and extendsthrough the sleeve 31 upon which the worm gear 32 is formed and on theend of the shaft a notched-plate 33, is secured, the said plate beingadapted to be engaged byteeth 34 formedon the clutch mem Jer 35 which isslidably connected to the sleeve 31 by a spline or feather connection.Mounted on the inner side of either of the members 19 and are the bevelgears 36 'and37, and a bevel pinion 38 is slidably mounted between thesebevel gears 36 and 37.

The bevel pinion38 has a bearing in a bracket or casing which iscomposed of two parts 39 .-and 40, and connected to said bevel pinion is.the gear 41 which meshes With the gear 42,

connected to the worm gear 43 which in turn meshes with and is driven.by the worm 32,

on thesleeve 31.

tively locked, although {twill be seen that were theshaft 25 connectedwith the sleeve 31, through the clutch member which is actuated by thehandle 44, the said worm 32 would be prevented from turning m the shaft25, thereby through its connecting gearing; preventing the revolution ofthe bevel pinion 38, whereby the two members 19 and 20 would be relathe, .entire drum 3 could be rotated by revolving the shaft 25.

, lower end passes around Should it be desired to raise or lower thecarriage, the handle 44 is moved to such a position that the teeth 45 onthe clutch member 35 would engage teeth 46 on the sprocket wheel 47 atwhich time "the teeth 33 would be disengagedfrom the teeth 34 there byfreeing the sleeve 31 from the shaft 25 when the said shaft, being heldby the rack 27 and pinion 26 would be prevented from turning, but therotation of the sprocket wheel'47 would rotate the worm 32 which 1'would, through its connecting gearing rotate springs handle '53 isprovided on the machine for the purpose of controllingfthe movement ofthe ram 28-whi'ch operates the rack 27.

' The carriage support operates in the usual manner over suitable guides54 formed in the frame of the machine and in. order that-the chains 10and 11 may be relieved of the weight of said carriage and rake when thesame is not being raised or lowered, the

frictionsupport such as illustrated in Figs. 4 and 5 is-p'rovided. Thissupport consists of the four levers, 55, 55 and. 56, 56,'thelevers 55,55, of which are pivoted to the ad justable pin-57 and extend across thecenter of the machine and carry between their outer ends the shoe 58which is adapted to normally bear againstthe guide, 54 at a pointslightly below the center at which the levers are pivoted. The levers5.6, 56, are similarly;

pivoted'to the adjustable pin 59 and carry a corresponding shoe 60.These levers are all held in their upper position, whereby the shoes 58and 60 are forced against the guides by adjustable springs 61 and 62 andthe adjustment of the pins 57 and 59 is secured by mounting the ends ofsaid pins in sliding blocks 63, the position of which is regulated bythe toggle joint 64, which has its central joint regulated by the.screws 65 and 66. The adjustment of these screws will take'up any unduewear of the shoes 58 and 60.

In order that the pressure of the shoes on the guides may be relievedwhen it is die sired to raise or lower the carriage, the lever 67, whichis pivotally mounted on the pin 59 is provided, and a roller, 68,carried on the inner end of said lever bears against the upper edge ofone of the levers 55; a pin 69, provided in one of the levers 56 bearsagainst the under side of the lever on which the roller rests. It willbe seen that by this arrangement depression of the roller 68 will forcethe levers 55 and 56 against the tension of'the 61 and 62, thusrelieving the pressure of the shoes 58 and 60 on the guides.

The roller 68 is depressed by'the movement of the slide 70011 the roller71 secured to the lever 67, said movement of the slide being effected bydepressing the lever 72 on which the bell crank 73, connected with thelower end of the slide, is formed, the upper portion of the slide beingmoved by the bell crank 74 which is connected to the lever 72 by thelink 75. The forcing over of this slide 70 will elevate the roll 71 anddepress the roll 68 at whatever elevation the roll 68 may be in theslide.

The ordinary water tank 76 is carried on the machine for the purpose ofcooling the rake and a sectional guard is provided on the forward end ofthe machine, as indicated at 27 in Fig. 1..

I claim as my invention and desire to secure by Letters Patent:

1. In a gas retort drawing machine, the

combination ofa rake slidably mounted in the frame of the machine, adiflerential drum mounted in the frame of the machine and flexibleconnections between said rake. and

said diflerential drum.v I

2.- In mechanism for elevating and reciprocating the rake of a gasretort drawing .machine, the combination of a drumjormed in twosections, means to interlock said sec tions, a flexible connectionsecured to the outer end of said rake and carried over one of thesections of said drum in one direction, a flexible connection secured tothe ou ter-end of said rake and carried over the other secbleconnections between said rake and said drum, and means to hold'the rakeand carriage at different positions independently of said flexibleconnections.

, 4. In mechanism for elevating and reciprocating the rake of a gasretort drawing machine, the combination of a drum-formed in tions, a,flexible connection secured to the outer'end of said rake and carriedover one of the sectionsof said drum in one direction, aflexible'connection 'secured'to the outer end tion of said drum in anop' osite direction, and means for cooling'the ra e.
